Storage of hazardous substances with spill sumps
WHY A SUMP?
The function of a sump is to protect underground water beds from hazardous polluting substances in case of leaks. This secondary containment system is able to prevent and reduce pollution.
The sumps’s minimum volume should be equal to the biggest of the stored container volume and not less than one third (1/3) of the total volume stored. Wherever substance storage is located in an underground water protect area, it is specified that the entire stored volume is to fit inside the sump (100%).
